It was the sixth-seeded Bulgarian's fourth title of the year and eighth career. Dimitrov will be ranked No. 3 when the year-end ATP rankings come out Monday.

"This makes me even more locked in, more excited about my work and for what's to come," Dimitrov said. "It's a great platform for me to build on for next year. It's going to be amazing in the offseason. I know what I have to do in order to do good."
